| /** |
| * Function: omxVCM4P2_MEInit (6.2.4.1.2) |
| * |
| * Description: |
| * Initializes the vendor-specific specification structure required for the |
| * following motion estimation functions: BlockMatch_Integer_8x8, |
| * BlockMatch_Integer_16x16, and MotionEstimationMB. Memory for the |
| * specification structure *pMESpec must be allocated prior to calling the |
| * function, and should be aligned on a 4-byte boundary. Following |
| * initialization by this function, the vendor-specific structure *pMESpec |
| * should contain an implementation-specific representation of all motion |
| * estimation parameters received via the structure pMEParams, for example |
| * rndVal, searchRange, etc. The number of bytes required for the |
| * specification structure can be determined using the function |
| * omxVCM4P2_MEGetBufSize. |
| * |
| * Input Arguments: |
| * |
| * MEmode - motion estimation mode; available modes are defined by the |
| * enumerated type OMXVCM4P2MEMode |
| * pMEParams - motion estimation parameters |
| * pMESpec - pointer to the uninitialized ME specification structure |
| * |
| * Output Arguments: |
| * |
| * pMESpec - pointer to the initialized ME specification structure |
| * |
| * Return Value: |
| * |
| * OMX_Sts_NoErr - no error |
| * OMX_Sts_BadArgErr - one or more of the following is true: |
| * - an invalid value was specified for the parameter MEmode |
| * - a negative or zero value was specified for the |
| * parameter pMEParams->searchRange |
| * |
